   1 /** @file
   2   SMM Fault Tolerant Write protocol is related to EDK II-specific implementation of FTW,
   3   provides boot-time service for fault tolerant write capability for block devices in
   4   EFI SMM environment.  The protocol provides for non-volatile storage of the intermediate
   5   data and private information a caller would need to recover from a critical fault,
   6   such as a power failure.
